VITAMINS A and D are fat-soluble Vitamins that are essential to our health and are frequently found together in nature.

Vitamin A has many different functions. First it is related to the maintenance of normal vision in dim light or the prevention of night blindness. It also aids in the growth and formation of body cells, making it essential for body growth. It is especially needed for bone growth. If the intake is not sufficient, bones will stop growing before the soft tissues are fully mature.

Vitamin A is also needed for normal tooth development because the enamel-forming cells are affected by lack of Vitamin A. It is also important in the maintenance of healthy epithelial tissues. There are two kinds of epithelial tissues: (1) those that cover the outer surface of the body - the resistant, protective skin (epidermis), and (2) those that line all the mucous membranes. Without Vitamin A, the epithelial cells become dry and flat and gradually harden to form scales that shed. Vitamin A is also necessary for the health of the membranes lining the stomach, intestinal wall, bladder and urinary passages and for the health of the sex glands and uterus. Lastly, Vitamin A works better where there are sufficient levels
of Zinc and an adequate intake of Protein.

Vitamin D is required for Calcium and Phosphorus absorption and utilisation. It is necessary for growth, development and maintenance of bones and teeth in adults and children. In its active form, Vitamin D works with Calcium to control bone formation. Vitamin D is unique in that man and animals normally obtain it from two sources: the spontaneous formation in the skin by the sun via a photochemical reaction in the epidermis, and eating from a food that contains Vitamin D.
